Model Development and Application at CCCma John Scinocca CCCma Model Development and Application Past: Focus was on two sequential activities: ● model (physics) development – atmospheric (AGCM) – ocean (OGCM) ● model application (CMIP/IPCC) – finalize AGCM and OGCM – tune CGCM – set up and execute climate projection runs each required an enormous technical effort and so model development and application were performed sequentially on the IPCC cycle (~5-7y) problematic: – model development is never finished – tight time line meant CGCM was never well tested – not a viable approach for the increasing number and complexity of applications (science, policy, MIPS, operations) Model Intercomparison Projects (MIPs) 2000 01 02 03 04 ARM GCSS 05 06 07 08 CCMVal-1 09 CCMVal-2 CMIP3/IPPC4 MPACE 10 2012 CORDEX CMIP5/IPPC5 CMIP5/IPPC5 GCSS WG1 CHFP CMIP5 Decadal GLACE-2 CFMIP MPACE Application/MIP Type 11 SHFP GCSS WG2 IceHFP CFMIP phase 2 GeoMIP ISVHE GCPI Climate projections AEROCOM Phase II Chemistry Climate Modelling CIRC Seasonal/Decadal Prediction TWP–ICE ACCMIP Model development AGCM CGILS MJO–MIP Model development SCM CMIP5 AMIP CMAM30 CCMI ● CCCma participated ~25 MIPs over the last decade ● number and complexity of the MIPs has been increasing steadily over the last few years.

Application of CCCma models in support of Network Projects ● CCCma and Network partners collaborate on design of experiments and simulations – define work required to set up model to perform experiments – define output required (relative to CMIP5) ● CCCma scientists work with support staff to perform experiments – schedule work required to set up end execute model simulations – execution of simulations undertaken by support staff – model is executed and diagnosed creating time series on-the-fly based on CMIP5 protocols ● experiment output, in the form of NetCDF time series data, is made available to network partners through public ftp from CMC servers
